Abstract

L'invention concerne un procédé pour préparer une dispersion stable d'amidon dilué par enzyme, caractérisée en ce qu'elle possède un degré de dilution sélectionné, qui consiste: (a) à combiner un amidon granulaire dérivatisé avec une enzyme alpha-amylase pour former une suspension amidon / enzyme; (b) à faire passer la suspension amidon / enzyme à travers un cuiseur à jet dans des conditions sélectionnées pour gélatiniser l'amidon; (c) à traiter la suspension amidon / enzyme pour mener à terme la gélatinisation et arriver à un degré de dilution sélectionné, de manière à ce que la concentration du produit d'hydrolysat d'amidon ayant un poids moléculaire supérieur à 1 000 000 de daltons soit de 5 % ou supérieure; et (d) à désactiver l'enzyme.
